Texas Instruments VSP5621
The VSP5620/21/22 are high-speed, high-performance, 16-bit analog-to-digital-converters (ADCs) that have four independent sampling circuit channels for multi-output charge-coupled device (CCD) and complementary metal oxide semiconductor (CMOS) line sensors. The VSP5620/21/22 include a programmable gain to support the pixel level inflection caused by luminance and a built-in light-emitting diode (LED) driver to adjust the brightness. The integrated digital-to-analog-converter (DAC) can be used to adjust the offset level for the analog input signal.| Part No. | VSP5621 |
